commit 693e0cb052 upstream.
While enabling these machines, we found we would sometimes lose an
interrupt if we change hardware volume during playback, and that
disabling msi fixed this issue. (Losing the interrupt caused underruns
and crackling audio, as the one second timeout is usually bigger than
the period size.)
The machines were all machines from HP, running AMD Hudson controller,
and Realtek ALC282 codec.

timeout(10 seconds). Even if the sleep process wake up by timeout, by this

commit c9a6338aec upstream.
In case a single HDA card has both HDMI and S/PDIF outputs, the S/PDIF
outputs will have their IEC958 controls created starting from index 16
and the HDMI controls will be created starting from index 0.
However, HDMI simple_playback_build_controls() as used by old VIA and
NVIDIA codecs incorrectly requests the IEC958 controls to be created
with an S/PDIF type instead of HDMI.
In case the card has other codecs that have HDMI outputs, the controls
will be created with wrong index=16, causing them to e.g. be unreachable
by the ALSA "hdmi" alias.
Fix that by making simple_playback_build_controls() request controls
with HDMI indexes.
Not many cards have an affected configuration, but e.g. ASUS M3N78-VM
contains an integrated NVIDIA HDA "card" with:
- a VIA codec that has, among others, an S/PDIF pin incorrectly
labelled as an HDMI pin, and
- an NVIDIA MCP7x HDMI codec.

commit 3690739b01 upstream.
AD1986A codec is a pretty old codec and has really many hidden
restrictions. One of such is that each DAC is dedicated to certain
pin although there are possible connections. Currently, the generic
parser tries to assign individual DACs as much as possible, and this
lead to two bad situations: connections where the sound actually
doesn't work, and connections conflicting other channels.
We may fix this by trying to find the best connections more harder,
but as of now, it's easier to give some hints for paired DAC/pin
connections and honor them if available, since such a hint is needed
only for specific codecs (right now only AD1986A, and there will be
unlikely any others in future).

commit d59915d065 upstream.
By trial and error, I found this patch could work around an issue
where the headset mic would stop working if you switch between the
internal mic and the headset mic, and the internal mic was muted.
It still takes a second or two before the headset mic actually starts
working, but still better than nothing.
Information update from Kailang:
The verb was ADC digital mute(bit 6 default 1).
Switch internal mic and headset mic will run alc_headset_mode_default.
The coef index 0x11 will set to 0x0041.
Because headset mode was fixed type. It doesn't need to run
alc_determine_headset_type.
So, the value still keep 0x0041. ADC was muted.

commit 2ded3e5b61 upstream.
The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself. But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls. This is a regression
compared with the previous static quirks.
This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.

commit ced4cefc75 upstream.
When a headphone jack is configurable as input, the generic parser
tries to make it retaskable as Headphone Mic. The switching can be
done smoothly if Capture Source control exists (i.e. there is another
input source). Or when user explicitly enables the creation of jack
mode controls, "Headhpone Mic Jack Mode" will be created accordingly.
However, if the headphone mic is the only input source, we have to
create "Headphone Mic Jack Mode" control because there is no capture
source selection. Otherwise, the generic parser assumes that the
input is constantly enabled, thus the headphone is permanently set
as input. This situation happens on the old MacBook Airs where no
input is supported properly, for example.
This patch fixes the problem: now "Headphone Mic Jack Mode" is created
when such an input selection isn't possible.

commit fc7dc61d9a upstream.
Unbalanced calls to snd_imx_pcm_trigger() may result in endless
FIQ activity and thus provoke eternal sound. While on the first glance,
the switch statement looks pretty symmetric, the SUSPEND/RESUME
pair is not: the suspend case comes along snd_pcm_suspend_all(),
which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
This way userland may provoke an unbalanced resume, which might cause
the fiq_enable counter to increase and never return to zero again,
so eventually imx_pcm_fiq is never disabled.
Simply removing the fiq_enable will solve the problem, as long as
one never goes play and capture game simultaneously, but beware
trying both at once, the early TRIGGER_STOP will cut off the other
activity prematurely. So now playing and capturing is scrutinized
separately, instead of by counting.

commit 0fc28fc030 upstream.
When a codec is resumed, it keeps the power on while the resuming
phase via hda_keep_power_on(), then turns down via
snd_hda_power_down(). At that point, snd_hda_power_down() notifies
the power down to the controller, and this may confuse the refcount if
the codec was already powered up before the resume.
In the end result, the controller goes to runtime suspend even before
the codec is kicked off to the power save, and the communication
stalls happens.
The fix is to add the power-up notification together with
hda_keep_power_on(), and clears the flag appropriately.

commit d183b4fc46 upstream.
snd_hda_codec_reset() is called either in resetting the whole setup at
error paths or hwdep clear/reconfig sysfs triggers. But all of these
don't assume that the power has to be off, rather they want to keep
the power state unchanged (e.g. reconfig_codec() calls the power
up/down by itself). Thus, unconditionally clearing the power state in
snd_hda_codec_reset() leads to the inconsistency, confuses the further
operation. This patch gets rid of the lines doing that bad thing.

hdmi_setup_fake_chmap() is supposed to set the reported channel map when

However, the function indexes channel_allocations[] with a wrong value
and extracts the wrong nibble from hdmi_channel_mapping[], causing wrong

Fix those issues.
Tested on Intel HDMI to correctly generate various channel maps, for
example 3,4,14,15,7,8,5,6 (instead of incorrect 3,4,8,7,5,6,14,0) for
standard 7.1 channel audio. (Note that the side and rear channels are
reported as RL/RR and RLC/RRC, respectively, as per the CEA-861
standard, instead of the more traditional SL/SR and RL/RR.)
Note that this only fixes the layouts that only contain traditional 7.1
speakers (2.0, 2.1, 4.0, 5.1, 7.1, etc.). E.g. the rear center of 6.1
is still being shown wrongly due to an issue with from_cea_slot()
which will be fixed in a later patch.
